About

Frontend engineer with 4+ years building production-grade web apps used by 200,000+ users across fintech, PropTech, and SaaS platforms. I ship fast, accessible, and maintainable UIs — not just components. At The Lettings Hub (UK PropTech, part of Canopy), I improved Core Web Vitals by 25%, cut redundant API calls by 30%, and helped push automated test coverage above 85% — across a React + Next.js + Angular + TypeScript stack. I've also implemented XSS/CSRF protection, Content Security Policy, and WCAG 2.2 AA compliance at the platform level. I think in systems: reusable component libraries, scalable state management with Redux, REST + GraphQL integration patterns, CI/CD pipelines, and performance budgets. I'm equally comfortable in Angular as I am in React, and I've shipped across the full frontend lifecycle — from architecture decisions to Lighthouse scores. Recently accepted into the Toptal global talent network (top 3% of applicants screened). 🔧 Stack: React 18/19 · Next.js · TypeScript · Angular · Redux · GraphQL · Node.js · Docker · AWS · PostgreSQL · Jest · React Testing Library 📍 Open to frontend / full-stack SDE-2 roles — Hyderabad | Bangalore | Remote
